/ˈreɪʃ(i)oʊd/

Origin: Formed within English, by derivation. Etymons: ratio n., -ed suffix².

Etymology: < ratio n. + -ed suffix². Compare earlier ratioing n. and later ratio v.

Expressed as a ratio or in terms of a ratio; enlarged or reduced by a certain ratio; subjected to ratioing.

ΚΠ

1914 Philos. Trans. (Royal Soc.) B. 205 451 Mean ratio of the high-ratioed member of the 13 pairs.

1943 H. T. U. Smith Aerial Photographs viii. 352 Ratioed print, a print prepared at a predetermined scale by photographic enlargement or reduction.

1981 Sci. Amer. Oct. 145/2 A computer can be programmed to divide the brightness of each point in the green image by the brightness of the corresponding point in the red image; the result is a ‘ratioed’ image that accentuates the forest more than either of the original images did.

1989 Nature 19 Oct. 591/2 To achieve the highest accuracy, we analysed ‘ratioed’ spectra (calculated by dividing spectra obtained at different altitudes) to eliminate instrumental effects.

1993 Jrnl. Field Archaeol. 20 83 A ratioed image can compensate for topographically induced brightness variations.
